Hi,

I have an Astra 1.7 CDTI - it is a Van Derived Car.

The issue im having is when i drive steady its fine but if i change gear and accelerate fairly fast, it CLUNKS, Rattles and the car jolts back and forward and PUFFS out WHITE SMOKE, the jolting is as if im just really gently tapping the brake.

Ive read online that it could be the Head Gasket or a Cracked Cylinder Head. If i put some of this in,
